Long Optical Path Length Thin-Layer Spectroelectrochemistry. Catalytic Oxidation of Hydroquinones by Oxygen at Platinum

Article abstract of DOI:10.1246/cl.1987.231

A clean, open-circuited Pt electrode, in the presence of dissolved oxygen, catalyzes the oxidation of hydroquinones in 1 M H2SO4.The oxidation rate is independent of hydroquinone, but dependent upon O2 concentration.If iodine is preadsorbed onto the Pt surface, the catalysis is inhibited, although reversible electron transfer to electrolyze the dissolved hydroquinone is not.
